Answer:
77.6
Step-by-step explanation:
The ratio of light times will be the ratio of distances:
(light time to Neptune) / (light time to Mercury)
= (Neptune distance)/(Mercury distance)
= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598
≈ 77.6
It takes about 77.6 times as long for light to reach Neptune as it does to reach Mercury.
Answer:
y is 4
Step-by-step explanation:
so the equation is y = kx ( k is the constant)
We've been given x as 5 & y as 10 so we can use these values to find the constant .
10 = k(5)
k = 2
so now , we can find y
y = 2 × 2
y = 4
Answer:
65 miles
Step-by-step explanation:
y=55+0.35x
77.75 = 55+0.35x
77.75 - 55 = 0.35x
22.75 = 0.35x
22.75 ÷ 0.35 = 0.35x ÷ 0.35
65 = x
x = 65
Answer:
9 arms
Step-by-step explanation:
6 eyes = 2 eyes three times (3 x 2), so three arms 3 times (3 x 3) = 9
